Question

Suppose you have a bag containing two red marbles, two blue marbles, and two white marbles. You choose two marbles without looking. *What is the probability that you will choose a red marble and then a blue marble without replacing the red one

Answer 1

Like they said the answer is 2/15

Answer 2

2/15

Explanation:

The probability of choosing a red marble first is 2/6, since there are two red marbles and six marbles in total.

Then the probability of choosing a blue marble next is 2/5 since there are 2 blue marbles but only 5 marbles left as you already took one out.

Therefore we can multiply 2/6 and 2/5 to get...

2/15
